HENRY DE MONTIN, OF LONDON, ENGLAND, ASSIGNOR OF ONE-HALF TO TI-IE SIMULTANEOUS COLOR PRINTING SYNDICATE, LIMITED, OF SAME PLACE.

PoLvCHRoME-PRlNTiNe MACHINE..

SPECIFICATION forming part of Letters Patent No. 628,719, dated July 11, 1899.

Application led DecemberQ 1898. Serial No. 698,776. (No model.)

Be it known that I, HENRY DE MONTIN, a subject of 'the Queen of Great Britain, residing at New Southgate, London, Middlesex county, England, have invented new and useful-Improvements in and Relating to Polychrome-Printing Machines, (for which I have applied for a patent in Great Britain, No. 10,153, dated May 3, 1898,) of which the following is a speciiication.

This invention relates to polychrome-printing machines in Which the colors to be used are formed in a solid block and to the preparation of the color-blocks Where heat is employed for rendering the block fluid to `give oft' color to the printing-paperor the like.

In the accompanying drawings, Figure 1 is a sectional plan of a portion of a single-cylinder printing-machine having my improvements applied thereto. Fig. 2 is a sectional end elevation, and Fig. 3 a longitudinal section, of the said machine; Fig. 4c is a section on the line i 4, Fig. l; and Figs. 5 and 6 are views of details. Figs. 4, 5, and ti are drawn to alarger scale than Figs. l, 2, and 3.

A is the frame of the machine, and B is the slidin g box or coiiin supported upon rollers B/ B2, mounted in the frame A, and carrying the bed C, supporting the color-block D, all these parts being of ordinary construction.

According to the invention I provide improved means for feeding the color-block after each im pression. Such means comprises a cross-shaft a, which is journaled in bearings a a formed in'the sliding box or cofiin B, the said shaft a being provided with worms i c 4c are worin-wheels with which the worms engage, the said Worin-Wheels being mounted upon spindles c c', carried by brackets c2 c2, secured to the sliding box or coffin B. The spindles c' carry toothed pinions c3, which engage With toothed wheels c4, mounted upon side shafts c5, carrying bevel-wheels c6, which gear with bevel-wheelslci', keyed to the nuts o8. These nuts c8 when rotated actuate the elevating-screws E, with which the bed O of the machine is provided, in the usual manner.

CZ is a ratchet-wheel which is provided upon the cross-shaft a, the said ratchet-wheel being lmined size.

.to the desired thickness of color to be removed from the color-block at each printing operation, the stop f is fixed in a slot f2 in the said bracket f so that its position in the said slot can be suitably adjusted. With this arrangement when the sliding box or coffin B reciprocates in the usual manner under the printing-cylinder F the lever e' by virtue of itsown weight assumes a vertical position and on the return movement of the sliding box or cofiin B strikes against the ixed stop f, so as to turn upon the cross-shaft a, and thereby engage with and rotate the ratchet- Wheel d and the said cross-shaft a through a distance which is dependent upon the position to which the said stop f has been adjusted.

I also provide a frame or chase through which the color-block D is forced as required `bymeans of the rising bed O, the said frame being adjustable according to the size of the block instead of being of a fixed or deterangle-irons g g, supported upon two longitudinal bars h h in the box or coffin B of the machine and forming two opposite sides of the frame. These longitudinal bars 7i 7i, .are

'provided with dovetailed grooves 7L h', and

they are secured to the box or cot'iin B by means of bolts 7b2, which pass through the ends of the bars h and the heads of which fit into dovetailed grooves h3 h3 in the sides h4 of the box or coffin B. It will be obvious that by sliding the bolts h2 in the dovetailed grooves 71.3 the distance between the two longitudinal bars h 7i can be adjusted as desired. h5 h5 are wing-nuts by means of which the vsaid bars h 7i are secured in any position to which they may be adjusted. The crossbars or angle-irons g g are provided with a number of holes g' g', by means ot' which they can be secured to the longitudinal bars h h through the medium of bolts g2 g2, which pass It consists of two cross-bars or IOO through the said holes g and the heads of which fit the dovetailed grooves 7L in the said bars 71, h, being secured in position by wingnuts g3 g3. The other two sides of the frame or chase are formed by two bars 'L' i, each of which consists of two or more overlapping parts, as shown clearly in Figs. 4 and 5, the latter of which figures is an end view of the former. The two ends t" 7l of the bars i i are bent at right angles to the main portions thereof and are adapted to be secured to the upright flanges of the angle-bars g g by Winged studs i2 i2, which pass through slots 3, Fig. 4, in the ends t" and holes g4 g4 in the said angle-bars g g. The overlapping end of one part of the bars it' is slotted and is adaptedto be secured to the other overlapping end by a bolt i4, having a Wing-nut i5. lVith this arrangement it will be obvious that the sides of the framel or chase can be adjusted in both directions by unscrewing the various wingnuts and studs, sliding the bars to the required position, and then again tightening the Wing-nuts and studs.

Instead of a gasheated printing-cylinder I employ a cylinder adapted to be heated by steam, hot Water, `or hot air. For this purpose the cylinder F is provided with a heatingjacketj, the heating medium passing through the cylinder-shaft j', which is made hollow. Tight joints are made between the ends of the shaftj and the pipes jz, conveying the heating medium, by suitable means, such as the stufng-box and gland jg. (Shown in Fig. 6.) Instead of the heating-jacket I may provide the cylinder]` with longitudinal heating-tubes arranged in proximity to the surface of the cylinder and extending between chambers at each end thereof, or a coiled tube could be used.

The color-blocks used in connection with printing-machines of the kind above described are made up of different coloring materials arranged mosaic-like in any desired design, and an impression is taken of the latter in all the colors simultaneously or by one impression. I employ animproved medium for combining with the coloring-matters or pigments to be used. This medium consists of mineral or earth Wax, vegetable and animal wax, animal, vegetable, and mineral oils,

and a small proportion of animal fat. The proportions of these ingredients which I have found to give good results in practice are as follows, viz: Eight parts of Japanese wax, two parts of cerosin-Wax, one .part of castor-oil, and one part of mutton fat, although it will be understood that these proportions may be varied as required for the different colors. These ingredients are melted and well mixed, and the compound formed is then mixed individually with the several coloring-matters previously ground, the said compound and' coloring-matter being mixed in about equal proportions by weight. The several coloringmatters so made are formed into a mosaic-like block according to the desired design, and after the block has been planed or rendered.

perfectly even of surface and in thickness it is ready for use in the printing-machine in the ordinary manner. The sliding box or cofn is reciprocated in the'usual manner.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare thatwhat I claim is l. In a polychrome-printing machine, the combination with the main frame of a reciprocating box mounted therein, a verticallymovable color-block support carried by said box adjustable guides secured to said box, and adjustable laterally and 'transversely thereof to engage color-blocks of diiferent sizes, and automatic mechanism for elevating said support whereby the color-block will be forced upward between said adjustable guides, substantially as described.

2. In a polychrome-printing machine, the

combination with the main frame, of the co1or block-carrying box, provided with parallel slotted portions adjacent'to opposite sides of the same, the vertically-movable color-block support mounted in said box, parallel slotted plates engaging said portions, of the box and provided with securing devices engaging said slotted portions, a pair of parallel guide-plates lying upon said slotted plates transversely thereto, and provided with vertical portions to engage the color-block and with adjusting devices engaging said slotted plates and a pairoflongitudinally-adjustableguide-plates lying upon, secured to and disposed transversely of the irst-named guidefplates, substantially as described.

3. In a polychrome-printing machine, the

combination with the main frame, of the colorblock-carrying box, provided with parallel slotted portions adjacent to opposite sides of the same, the vertically-movable color-block support mounted in said box parallel slotted plates engaging said portions, of the box and provided with securing devices engaging said slotted portions, a pair of parallel guide-plates IOO IIO

lying upon said slotted plates transversely 4 means for securing said end portions adjustl ably to the vertical portions of said first-n amed guide-plates, substantially as described.
